Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
In display technology, display units that display video and images are referred to as pixels. Generally, a pixel unit is composed of a smaller sub-pixel combination, and the number of the pixel array of the display screen and the resolution of the video or image to be displayed are consistent, that is, a certain pixel point in the video or image to be displayed is represented by a fixed pixel unit on the display screen. Generally, any color in the display field can be mixed by red, green and blue (RGB), that is, a pixel array is formed by continuously and repeatedly arranging R, G, B sub-pixels in a specific sequence. According to the method, researches show that if the high-resolution image to be displayed can be split into a plurality of low-resolution images, and the split low-resolution images are displayed in a specific mode within the display time of the original frame of high-resolution image. The use of memory resources may be reduced by processing the pixels in real time. This particular display, referred to herein as a real-time computing process, is described in more detail below.
The present invention provides a video display system with reduced storage capacity and improved display resolution, as shown in fig. 1, comprising a driving module and a display module. The driving module calculates pixel points in real time according to the selected display units, and then the display module displays the pixel points calculated in real time.
The driving module comprises a data real-time processing module, a control module and a display unit selection module, wherein:
and the display unit selection module is used for generating corresponding selection signals according to the selected display unit shape in the cfg configuration and sending the selection signals to the data real-time processing module.
A control module for decoding and converting the video source signal into video data with a predetermined format (such as RGB 888). And meanwhile, generating corresponding control signals, and sending the video data and the control signals to the data real-time processing module.
And the data real-time processing module is used for carrying out real-time data operation processing on the video data signals according to the frame synchronization signals and the line synchronization signals of the video source, and selecting a corresponding operation method for carrying out real-time processing according to the selection signals generated by the display unit selection module and the control signals generated by the control module in the real-time processing process.
The real-time computing processing method comprises the steps of dynamically combining 4 sub-images of a frame of image through different movements according to the shape of a display unit in a display screen, then computing pixel information after dynamic combination in real time to obtain new sub-pixel units at different positions, and displaying the new pixel units on a display module (display screen).
The invention realizes that the pixel unit of the image in the original video source is calculated and processed in real time to obtain a new pixel unit to be displayed on the display module.
The format of the video source includes but is not limited to RGB888, MIPI format, HDMI format, etc.; the hardware platform adopted in the specific implementation process is various, including but not limited to an FPGA, a video display processing chip, a GPU, and the like. After receiving a video source signal, the system decodes the data format of the video source according to the video source format, decodes the video source into the data format of RGB888, and selects a suitable data processing method according to the configured display unit format (display unit state), where a small part of data (data to be processed by the data real-time processing module) needs to be cached for the subsequent data real-time processing module to perform processing operation.
As shown in fig. 2_ a, which is a schematic structural diagram of a driving module, first, data format conversion is performed on input video source data to convert the input video source data into RGB888 data format. The data operation method used will be different for different display unit shapes, so that a suitable data processing method is selected according to the configured display unit shape (format), and the specific data processing method will be described in detail below.
Fig. 2_ B is a schematic diagram of a display module structure. The display screen includes j × k display cells (i.e., pixel cells). After the data receiving and processing module receives the data of the display screen, firstly, a whole line of data (k pixels) is correspondingly sent to each data latch unit/driving unit, at this time, the data receiving module opens the corresponding address selecting/driving module according to the analyzed address information, the data stored in the data latch/driving unit is sent to the corresponding pixel, then the address selecting/driving module is closed, and the data is latched on the pixel point of the display screen. Subsequent data is displayed on the pixels in the same manner.

As shown in fig. 3_ a-3_ E, fig. 3_ a is a video source image with a resolution of 2j × 2k, and fig. 3_ B is a video source image with odd rows and odd columns of pixels to form sub-images 1 with a resolution of j × k; fig. 3_ C shows that pixel points are captured from the original video source image in odd and even rows to form sub-image 2, where the resolution is j × k; FIG. 3_ D shows the original video source image with pixel points in odd rows and even columns to form sub-image 3, with resolution j × k; fig. 3_ E shows the original video source image taking pixels in even rows and even columns to form the sub-image 4, with the resolution j × k.
